     2. Decide where your team will meet off campus to design and to possibly build your
     3. Delegate tasks WITH DUE DATES!
     4. Don’t procrastinate! DO IT!
     5. Exchange PHONE NUMBERS!!!!!!!!
     6. Exchange e-mail addresses!

      3. Team Member #3     ___________________ ______________________
      4. Team Member #4     ___________________ ______________________

Lab Days:
     1. There will be 2 lab days during the week to help your team to work on the rocket
        together. If the 2 lab days do not provide enough time for your team to complete
        the rocket, it is your TEAM RESPONSIBILITY to meet off-campus to complete the
     2. You must bring your own materials to the lab.
     3. You must store your materials IN YOUR LOCKER!
     4. Arrangements for the rocket itself to be stored in the lab can be made.

Proof of Rocket Stability:
      1. Each team MUST complete a computer simulation (software will be provided) that
          will calculate the safety and stability of your rocket design.
      2. Each team MUST have simulation results REVIEWED & APPROVED by the

     1. A limited amount of time is available for the launch of your rocket.
     2. One class period will be made available for teams to launch their rocket.
     3. Date for Rocket Launch will be __________________

Rocket Recovery Techniques:
     1. Floating-spin recovery

                          Bottle Rocket Project                                        Page 4


STEP 1.    Get Your Team ORGANIZED!
                  Who is your Team Leader
                  Who is responsible for what
                  Fill out the Index Card with your Team Name and Names of Team
                  Exchange PHONE NUMBERS!!!!!!!!
                  Exchange e-mail addresses!

STEP 2.    Decide on the type of Recovery System your team will base the design of your rocket
           upon. Obtain a progress / acceptance stamp.

STEP 3.    Agree upon what materials EACH MEMBER must bring for your team to begin
           building your rocket. Be sure to have all team members understand that if one
           person fails to bring what they agreed to bring, your team will be unable to
           build during lab time and must then make-up the lost time outside of class!

           You must plan ahead and be responsible for your actions / inactions.

STEP 5.    Establish a team hypothesis regarding your design goals and be
           sure to explain WHY. Obtain a progress / acceptance stamp.

STEP 6.    Make a DETAILED DRAWING of your team rocket. Be sure that all dimensions
           are shown. Use a PEN. Be NEAT. Obtain a progress / acceptance stamp.

STEP 7.    Build your rocket.

STEP 8.    Determine the C.G. (center of gravity) of your completed rocket. Draw the required
           symbol that identifies the C.G. of your rocket.
           Obtain a progress / acceptance stamp.

STEP 9.    Complete the “Rocket Stability Questionnaire”.
           Obtain a progress / acceptance stamp BEFORE using the computer.

STEP 10.   Enter the data from your “Rocket Stability Questionnaire” into the computer program
           to determine if your rocket is stable or not. If it is not stable, you must go back and
           change your rocket design to make it stable!
           You will not be allowed to launch an unstable rocket.

STEP 11.   Submit your final rocket WITH evidence that your design is stable to your instructor
           for your final progress / acceptance stamp AND GRADING of your rocket.

          How To Determine Your Rockets Apogee?
               Use Trigonometry of a Right Triangle!!!

                          c                a = Apogee of


                    b = x meters (distance from launch pad)

Tangent 0 =     side opposite 0 = a
              side adjacent to 0 = b

IF x = 50 meters, then:

tan 0 = apogee of rocket
           50 meters

apogee = (tan 42 ) (50 meters)

apogee = (0.90) (50 meters)
apogee = 45 meters
                                                                                                  Page 12
        a.   A lab report is to be completed by EACH TEAM MEMBER.
        b.   Your report is to be TYPED.
        c.   Your name must appear on every page! (including Period # and Table #)
        d.   Use proper grammar and be sure to check for any spelling errors!

Lab Report Questions:
Q1:     Explain how Newton’s 1 Law of Motion applies to the rocket during the following three phases of flight:
                .a. At launch
                .b. When the engine pressure becomes zero.
                .c. when it stops at the top and reverses its direction and begins to fall downward
                    ( 100 words minimum typed, not including your restatement of the question.)
Q2.     Explain how the rocket utilizes Newton’s 3 Law of Motion for:
                1. how the fins work
                2. the effect of the Center of Pressure on the rockets’ Center of Gravity
                3. (make a sketch to help explain both 1 & 2))
        ( 100 words minimum typed, not including your restatement of the question .)

Questions 3 thru 10 may be written using a pen)

Q3.     State what the average measured angle to apogee was for your rocket.
        Calculate the height of apogee in meters. (show your calculations in pen)

Q4.     State what the measured time from launch to apogee was for your rocket.

Q5.     Determine the average velocity of your rocket on its way up. (show your calculations!)

Q6.     Determine the average acceleration of your rocket on its way up. (show your calculations)
Q7.     Based upon the 2 law of motion, calculate the FORCE your rocket engine applied to the rocket
        during its flight up.        ( show your calculations)

Q8.     Determine the momentum of your rocket during its flight up. (show your calculations)

Q9.     Make a drawing of the rocket’s flight beginning at the launch pad. Using the drawing to help explain
        where the greatest AND least amount of Potential Energy existed during the flight of the rocket.
        Be sure the explain WHY it is so.

Q.10.   Using the same drawing from Question #9, explain where the greatest AND least amount of Potential
        Energy existed during the total flight of the rocket. Be sure to explain WHY it is so.

Q11.    Did your rocket perform as your team planned that it would? (Type a 50 word explanation of your
        observations. A “yes” or “no” answer is not acceptable)

Q12.    Identify 3 things that your team could have done to the design/preparation of your rocket that would
        have increased the distance that it traveled.
                 ( 100 words minimum typed, not including your restatement of the question .)

Q13.    Leadership and teamwork was a key learning opportunity during this project. What THREE (3) key
        things do you feel that your team should have done that would have made this project more
        successful? (PRINT a minimum of 50 words not including any restatement of the question)

Q14.    What did you learn about your team mates? Did each team member perform as you expected? What
        happened? (PRINT a minimum of 50 words not including any restatement of the question )
